How to Make Walnut Brittle

  1. In a large, microwave-safe bowl, combine 1 cup granulated sugar and ½ cup light corn syrup.
  2. Microwave on high for 3 minutes. Stir well to dissolve the sugar completely.
  3. Microwave for an additional 4 minutes. Stir again, ensuring all sugar is dissolved and the mixture is beginning to thicken.
  4. Remove from microwave and stir in 1 cup walnut halves, ¼ teaspoon salt, 1 teaspoon vanilla extract, and 2 tablespoons (1/4 stick) unsalted butter.
  5. Using an electric mixer, beat the mixture until it is light, fluffy, and well combined. This will take about 2-3 minutes.
  6. Lightly grease a baking sheet with butter or cooking spray.
  7. Spread the mixture evenly onto the prepared baking sheet to your desired thickness (about ¼ inch is recommended).
  8. Allow the brittle to cool slightly until it's firm enough to handle (about 10-15 minutes). Gently stretch the brittle to slightly increase its thinness and create a more delicate texture. (Optional)
  9. Let the brittle cool completely at room temperature for at least 1 hour, or until completely hardened.
  10. Once cooled, break the brittle into pieces and store in an airtight container at room temperature for up to 2 weeks.
